Radial line s lo t array antenna at 28 GHz with modified ... Available online 23 May 2017 Coaxial to waveguide transition adaptor with disk shaped terminated feed probe was found to be an effective feed network for single layer radial line slot array antenna. However, further studies with the feed probe terminated in none disk shaped elements is required. Design of a slot-coupled radial line helical array antenna ... An eight-ring radial helical array antenna based on a novel slot-coupled structure is designed and simulated. The novel coupling structure has the advantages of high power-handling capacity and excellent coupling ability. BANDWIDTH ENHANCED AND SIDELOBES LEVEL REDUCED RADIAL LINE ... Keywords: 5G, radial line slot array antenna, sidelobes level, 28 GHz. INTRODUCTION Over the years, interest in mobile data have and is still experiencing an unprecedented growth. This growth is further fuelled by the emergence of new data hungry devices like e-book readers, notebooks, smartphones, tablets etc. Radial Line Slot Antennas | Request PDF - researchgate.net

Among them, we employed the radial line slot antenna (RLSA) [21, 22] by changing the antenna size for THz waves and proposing a structure coupling to the RTD. In the integration of the RLSA and RTD, the oscillator structure can be simply composed of a substrate and two electrodes on and under it, except for the resonator and RTD.

A Reconfigurable Radial Line Slot Array (RLSA) Antenna for Apr 03, 2012 · A reconfigurable beam shape and broadside radiation pattern microstrip antenna is introduced in this paper. The antenna's radiating surface is designed using a radial line slot array (RLSA) arrangement, which is fed from an aperture coupled structure. This novel feeding structure for an RLSA antenna incorporates PIN diode switches which are integrated with the feed line structure to … A Reconfigurable Radial Line Slot Array Antenna for WiMAX A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application 55 achieves a higher gain in comparison to the divisive broadside pattern. Figure 8 depicts the 3D simulation of the far field radiation patterns of the proposed antenna which is aligned with the measured radiation patterns as shown in figure 6 and figure 7. However, the The Radial Line Concentric Slot Array Antenna of the antenna is the radial line waveguide0slot array antennas. This structure are made from two plate for radiating waveguide. In this research, based on the theoretical calculation of the hybrid feed structure composed of the circular waveguide and coaxial feed and ring slot, and patch structure and the radial line.
